Sorry if this has been asked previously. Occasionally our late 2011 iMac, (latest updated Lion OS X), wakes up by itself, and sits at the login screen. It is not consistent. p.s. Yes, I'm sure we haven't clicked the mouse or anything.

As always, I appreciate any feedback as I have learned a lot from this forum!
